To all whom it may concern:

Be it known that I, JAMES W. LESLIE, a citizen of the United States,residing in IVakefield, county of Middlesex, and State of Massachusetts,have invented an Improvement in Curtain-Rings and Traverse 'RollsTherefor, of which the following description, in connection with theaccompanying drawing, is a specification, like letters on the drawingsrepresenting like parts.

This invention has for its object the production of a novel cheap andeflicient ring for use in hanging curtains, portieres and the like, thering being provided with one or more traverse rolls whereby the easy andfree movement of the ring along the pole is facilitated.

The construction of the traverse roll and the mode of securing ormounting it in the body of the ring are comprehended in thenovel'features of my invention, to be fully described in the subjoinedspecification and particularly pointed out in the following claims.

Figure 1 is a front elevation of a curtain ring provided with traverserolls and embodying one practical form of my invention, the supportingrod or pole being shown in section; Fig. 2 is a greatly enlarged view,partly in section, of the traverse roll and parts cooperating therewith;Fig. 3 is an en-- larged section showing the two-part axle and theconstruction of the heads and enlargements thereon.

Referring to Fig. 1 I have shown the ring as provided with two traverserolls, as for general purposes such arrangement secures the bestresults, the annular ring-body 1 being made of thin sheet metal intubular form, as is customary. The ends of the body are separatedsufliciently, in this instance, to receive two traverse rolls and adistance piece 2, also of tubular sheet metal. The traverse roll may beof any suitable construction, but it is conveniently made of twocup-like pieces 3, 4, Fig. 2, of sheet metal, which are shaped or stained into shape, and one is forced within tiie other, as shown, an axialopening 5 being made in each side of the roll. I provide a two-partaxle, herein shown as two tubular or hollow studs 6, 7 providedrespectively with enlarged flat heads 6 7 best shown in Fig. 8, the stud6 being large enough to permit the stud 7 to be telescoped thereinto.The stud 7 is long enough to be upset at its inner end at 8, Figs. 2 and3, to lock the axle members together after they are telescoped. Atubular, sheet metal boss 9 having a contracted neck or external annulargroove 10 is secured to each stud head by spinning down the flange 11over the edge of e head, see dotted lines Fig. 3 and full lines Inpractice the stud head and boss are first connected as described, andthe construction of both the stud and the boss is a very simple andcheap operation, as the parts are quickly made by suitable dies, and byspinning and stamping operations well knownin the art. The two studscomprising an axle, with their attached bosses, are then inserted in thetrav erse roll from opposite sides thereof, the end of the outer stud,as 6, abutting against the head 7 as shown in Fig. 3, and then the endof the stud 7 projecting through the head 6 is upset by a suitable toolinserted through the open end of the adjacent boss 9. This locks thestuds together, with the roll rotatably mounted thereon between the twoheads 6 7 X the latterlimiting lateral play of the roll on the axlewithout any bending action. The assembled roll and axle are now readyfor connection with the ring-body, and when using two rolls the. boss onthe outer end of each axle is inserted in the adj acent open end of theringbody, and the tubular distance piece 2 is inserted between therolls, receiving the bosses at the inner ends of the axles.

The finishing operation is usually effected by compressing in suitabledies, the parts assembled as described being laid in one half of thedie. The other half is then applied, and the halves pressed together,and by so doing the metal of the ring-body is pressed into the grooves10, as at 12, Fig. 1, and the metal of the distance piece is compressed,at 12, into the grooves of the inner bosses. The ring is now completed,with the traverse rolls in proper position and securely locked in place.In some instances it may be most convenient to lock the distance-piecefirst, and thereafter lock the ring-body onto the bosses on the outerends of the axles.

My invention is not restricted to the precise construction andarrangement shown, nor to the particular number. of traverse rollsmounted on the ring-body.

I have omitted the roll in Fig. 3 in order to avoid confusing the otherparts illustrated therein.

Having fully described my invention,

Letters Patent is z- 1. In a curtain ring, a traverse roll, an axle onwhich it rotates, heads on the ends of the axle to limit lateral play ofthe roll, annularly grooved bosses on the heads, and a tubular ring-bodyhaving its ends embracing the bosses and compressed into the groovesthereof.

2. A tubular metallic ring-body, a traverse roll, an axle on which it isrotatably mounted, and annularly grooved enlargements on the ends of theaxle, to enter the open ends of the ring-body, the latter beingcompressed into the grooves to lock the axle and body together.

3. In a curtain ring, an annular, tubular, metallic body havingseparated ends, a plurality of traverse rolls, an axle for each, havingannularly grooved enlargements on their ends, the enlargement on theouter end of each axle being inserted. in the adjacent end. of the body,the latter being compressed in the groove to lock the body and axletogether, and a tubular distance piece embracing the enlargements at theinner ends of the axles and similarly locked thereon.

4. A traverse roll having an axial opening, a two-part tubular axleloosely extended therethrough, one part being telescoped into the other,an annular head on the outer end of each part, a hollow, externallygrooved boss compressed onto each of said heads, and means to lock theaxle parts together.

5. A traverse roll having an axial opening, an axle loosely extendedtherethrough and comprising two hollow studs one of which is insertedwithin the other and. upset at its inner end, to lock the partstogether, a head on the outer end of each stud, and an externallygrooved boss on each of said heads.

6. A traverse roll having an axial opening and an axle thereforconsisting of two tubular studs each having at one end an enlarged headand a boss connected therewith by a reduced neck, the studs beinginserted in the axial opening of the roll from opposite sides andtelescoped one within the other, the innermost stud being upset at itsinner end to lock the studs together, the outermost stud maintaining theheads separated.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
